At the invitation of Institute for Multidisciplinary Innovation, XU Jifeng, Chief Engineer of Aircraft Design from COMAC, attended the tenth lecture of "Truth-Seeking Forum" and delivered academic report --"Key Technology of Design and Manufacturing" in Jianlong Auditorium, and live online Tencent conference in the meantime. The report was chaired by Professor NIU Kangmin, head of the Composite Structural Engineering center.

XU Jifeng who is national special expert, supervisor of post-doctoral workstation at Commercial Aircraft Corporation of China, deputy chief designer and senior researcher of Beijing Civil Aircraft Technology Research Center at COMAC, director of Beijing Key Laboratory of Civil Aircraft Structure and Composite Materials; CR929 Engineering manager of the Widebody airliner composite structure integration team; project manager of the new model airframe integration team. Received bachelor, master, and doctorate degrees from Peking University, the Center for Systems Engineering of the Ministry of Aerospace Industry, and Carnegie Mellon University respectively.

In the report, XU Jifeng combined his own work to vividly elaborated technical issues related to the structure of civil aircraft. XU addressed that it usually takes more than ten years from program demonstration to putting into use of a new type aircraft. The design and manufacturing process of modern aircraft structures is a huge, complex, costly, and time-consuming system engineering, which involves a wide range of theoretical foundations and is extremely practical. From the aspects of material application, optimization design, strength analysis, process preparation, monitoring and maintenance, explained the key technical issues of civil aircraft structure design and manufacturing to the teachers and students.
